UINavigationController interactivePopGestureRecognizer working abnormal in iOS7

In iOS7, we have a new "swipe left to right" gesture, this is a very useful feature, but now I have a problem with it.

I use this code to custom the back button in UINavigationBar.

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:view];

but this will disables the "swipe left to right" gesture, so I use the follow code to keep the gesture enabled.

self.navigationController.interactivePopGestureRecognizer.delegate = self

And then, I found that the gesture is working abnormal, if current ViewController has a tableView, when the tableView is scrolling, the gesture won't be triggered. Now the gesture can't be triggered easily, is there some way to fix it?

Solution

  • This code can wroks well for me.

    - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldBeRequiredToFailByGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return [gestureRecognizer isKindOfClass:UIScreenEdgePanGestureRecognizer.class];
}
